Abstract: A semiconductor structure includes a semiconductor substrate, first to third isolation structures, and a conductive feature. The first to third isolation structures are over the semiconductor substrate and spaced apart from each other. The semiconductor substrate comprises a region surrounded by a sidewall of the first isolation structure and a first sidewall of the second isolation structure. The conductive feature extends vertically in the semiconductor substrate and between the between the second and third isolation structures, wherein the conductive feature has a rounded corner adjoining a second sidewall of the second isolation structure opposite the first sidewall of the second isolation structure.

Abstract: The present disclosure provides a method for manufacturing an auto-crosslinked hyaluronic acid gel, comprising conducting auto-crosslinking reaction of a colloid containing hyaluronic acid continuously at low temperature in an acidic environment, and treating the reaction product with steam at high temperature to obtain the auto-crosslinked hyaluronic acid gel with high viscosity.

Abstract: The present invention discloses a method for detecting whether cells are infected with human papillomavirus (HPV), and the method includes: (a) capturing a contour of a cell of a cell image, wherein the contour has a contour pixel thereon; (b) identifying a tangent of the contour pixel on the contour to define in relation to the tangent a first side and a second side opposite to the first side, wherein the first side indicates the intracellular region of the cell and the second side indicates the extracellular region of the cell; (c) calculating an optical parameter average of the plurality of pixels on both of the first side and the second side; and (d) determining whether the cell is infected with HPV based on whether the optical parameter average on the first side is smaller than that on the second side.
